Cm870 Turbo noise......new turbo?

Nialo thanks for some of the steps on checking the turbo. I can do regulated shop air to check the actuator, and probably should since the turbo is at this age.

Rawze thanks, that sure sounds like that could be it. I don't know when I'll get to work on it again, maybe Sunday night....but I'll start there. I've got 2 combine heads tore apart right now rebuilding a few parts.
